Abstract

''POTE DE REVESTIMENTO PARA REVESTIR UMA TIRA METáLICA COM UM METAL CONTENDO ZINCO, E, APARELHO DE REVESTIMENTO''. Um pote de revestimento com zinco para galvanizar uma tira de aço possui dois níveis ao longo de sua superfície inferior. O primeiro nível mais raso é localizado sob um cilindro de revestimento, criando assim uma área onde a taxa de fluxo de metal de revestimento com zinco em fusão é relativamente alta. As partículas de escumalha permanecem suspensas e não acumulam no fundo do pote de revestimento de zinco nessa região. Um segundo nível mais profundo é localizado em um lado do primeiro nível. Esse segundo nível cria um espaço no qual a taxa de fluxo de metal em fusão é menor do que a velocidade terminal das partículas de escumalha. Isso encoraja a sedimentação da partículas de escumalha nessa região. Fornece uma área de acúmulo para qualquer escumalha de fundo a ser removida posteriormente por um mecanismo de remoção de escumalha, tal como colheres mecânicas ou por bombeamento, sem a interrupção do processo de revestimento.'' COATING POT TO COVER A METALLIC STRIP WITH A METAL CONTAINING ZINC, AND COATING APPLIANCE ''. A zinc-coated pot to galvanize a steel strip has two levels along its bottom surface. The first shallowest level is located under a coating cylinder, thus creating an area where the flow rate of molten zinc-coated metal is relatively high. The scum particles remain suspended and do not accumulate at the bottom of the zinc coating pot in that region. A deeper second level is located on one side of the first level. This second level creates a space in which the flow rate of molten metal is less than the terminal velocity of the scum particles. This encourages sedimentation of scum particles in that region. It provides an accumulation area for any bottom scum to be removed later by a scum removal mechanism, such as mechanical spoons or by pumping, without interrupting the coating process.
